* This review takes up two fields (too long to fit into one) "In this book [Mukamel] has brought his many contributions together and has woven a fabric that brilliantly ties fundamental principles to experiment with an elegant formalism. This book is of extraordinary value to both the advanced student and researcher in the field. "[It] is written in such a way that it serves as both an advanced text as well as a reference book for the experimentalist. Prof. Mukamel has develped a very powerful unified correlation approach that is applicable to condensed phase systems as well the gas phase. The book provides Green's function techniques which are useful for interpreting nonlinear spectra of frequency and time domain nonlinear spectra of frequency and time domain complex systems. Several applications of current interest are treated in the book including Raman spectrocopies, photon echoes, pump-probe, hole burning, polarization spectroscopies, and impulsive effects. "Possibly the most important contribution made by this book is that it brings together the techniques of nonlinear spectroscopies with analytical and conceptual foundations that make an important step toward creating a new science for probing the properties of matter."-Charles V. Shank, Director, Lawrence Berkeley National Laboratory "I can recommend this book wholeheartedly both as a textbook in a graduate course in modern fast spectroscopy and as a reference monograph for researchers in the field."-Robert J. Silbey, Journal of the American Chemical Society
